Is my refrigerator in tune?
Cold cabinet listening protocol 4-C
A refrigerator is considered domestically in tune when its compressor returns to the same note after three ordinary door events.
- Listen from one counter away.
- Record the note before opening.
- Remove no magnets.
- Wait through the post-door sigh.
- Count rattles separately.
- Ignore ice during active descent.
Escalate: wet buzzing, a rising note lasting over 40 seconds, or a hum that follows you into another room.
